Résumé / Abstract
The Middle to Late Eocene Chumstick Formation comprises >12 km of fluvial and lacustrine strata deposited in a strike-slip basin in Washington State. The Chumstick paleoflora is a mixed suite of broad-leaved evergreen and broad-leaved deciduous taxa, with physiognomic characteristics intermediate between paratropical and subtropical rainforest types. The Chumstick paleoflora probably occupied an intermediate paleogeographic position between lowland and montane rainforest, in a setting about 150 km inland from the Pacific coast at elevations up to about 750 m. Most plant macrofossils are found in proximal overbank sequences or on the preserved tops of emergent mid-channel bars
